1. What Premax is and what it is used for

Pregabalin belongs to a group of medicines used to treat epilepsy, neuropathic pain, and generalized anxiety disorder (GAD) in adults.

Peripheral and central neuropathic pain: Premax is used to treat chronic pain caused by nerve damage. Various diseases can cause peripheral neuropathic pain, such as diabetes or herpes. The pain sensation may be described as warmth, burning, throbbing, shooting, stabbing, sharp pain, cramps, continuous pain, tingling, numbness, or prickling sensations. Peripheral and central neuropathic pain may also be associated with mood changes, sleep disturbances, fatigue (tiredness), and may affect physical and social activities and overall quality of life.

Epilepsy: Pregabalin is used in the treatment of certain types of epilepsy (partial seizures with or without secondary generalization) in adults. Your doctor will prescribe pregabalin when your current treatment does not adequately control your condition. You should take pregabalin in addition to your current treatment. Pregabalin must not be used as monotherapy, but should always be used in combination with other antiepileptic treatments.

Generalized anxiety disorder: Pregabalin is used to treat generalized anxiety disorder (GAD). Symptoms of GAD include excessive and prolonged anxiety and worry that are difficult to control. GAD may also cause restlessness or a feeling of being keyed up or on edge, easy fatigability (tiredness), difficulty concentrating or mind going blank, irritability, muscle tension, or sleep disturbance. This is different from the stress and worries of everyday life.

2. What you need to know before taking Premax

Do not take Premax

If you are allergic to pregabalin or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Consult your doctor or pharmacist before starting to take Premax

• Some patients treated with pregabalin have reported symptoms indicating an allergic reaction. These symptoms include swelling of the face, lips, tongue, and throat, as well as development of widespread skin rash. If you experience any of these symptoms, you must seek immediate medical attention.
• Serious skin rashes, such as Stevens-Johnson syndrome and toxic epidermal necrolysis, have been reported in association with pregabalin treatment. Stop taking pregabalin and seek immediate medical help if you notice any symptoms related to these serious skin reactions described in section 4.
• Dizziness and drowsiness have been associated with pregabalin, which may increase the risk of accidental injuries (falls) in elderly patients. Therefore, you should exercise caution until you become familiar with how this medicine affects you.
• Pregabalin may cause blurred vision, vision loss, or other changes in eyesight, many of which are transient. If you experience any changes in your vision, you must inform your doctor immediately.
• Diabetic patients who gain weight while taking pregabalin may require adjustments in their diabetes medications.
• Certain adverse effects, such as drowsiness, may be more frequent in patients with spinal cord injury, as they may be taking other medications for conditions such as pain or spasticity (tight or stiff muscles), which have similar side effects to pregabalin. This may increase the intensity of these effects when taken together.
• Cases of heart failure have been reported in some patients treated with pregabalin. Most of these patients were elderly and had cardiovascular diseases.

Before using this medicine, you must inform your doctor if you have a history of heart disease.

• Cases of kidney problems (renal failure) have been reported in some patients treated with pregabalin. If you notice a decrease in your ability to urinate during treatment with pregabalin, inform your doctor, as stopping the treatment may improve this condition.
• Some patients taking antiepileptic medicines such as pregabalin have had thoughts of harming themselves or of suicide, or have shown suicidal behavior. If at any time you experience such thoughts or behaviors, contact your doctor as soon as possible.
• When pregabalin is taken together with other medicines that may cause constipation (such as certain types of pain medications), gastrointestinal problems (e.g., constipation, intestinal blockage, or intestinal paralysis) may occur. Inform your doctor if you experience constipation, especially if you are prone to this problem.
• Before taking this medicine, inform your doctor if you have ever abused or been dependent on alcohol, prescription medicines, or illegal drugs; this may mean you have a higher risk of becoming dependent on pregabalin.
• Cases of seizures during treatment with pregabalin or shortly after discontinuation have been reported. If you experience seizures, contact your doctor immediately.
• Cases of reduced brain function (encephalopathy) have been reported in some patients taking pregabalin who also had other medical conditions. Inform your doctor if you have a history of serious illness, including liver or kidney disease.
• Cases of breathing difficulties have been reported. If you have disorders of the nervous system, respiratory disorders, renal failure, or are over 65 years of age, your doctor may prescribe a different dose. Contact your doctor if you experience difficulty breathing or shallow breathing.

Dependence

Some people may become dependent on Premax (a need to keep taking the medicine). They may experience withdrawal symptoms when they stop using Premax (see section 3, “How to take Premax” and “If you stop taking Premax”). If you are concerned about possibly becoming dependent on pregabalin, it is important to consult your doctor.

If you notice any of the following signs while taking Premax, it could be a sign that you have become dependent:

• You feel the need to take the medicine for longer than recommended by your doctor.
• You feel you need to take a higher dose than prescribed.
• You are using the medicine for reasons other than those for which it was prescribed.
• You have made repeated unsuccessful attempts to stop or control your use of the medicine.
• When you stop taking the medicine, you feel unwell and feel better again once you take it.

If you notice any of these signs, speak with your doctor to discuss the best care plan for you, including when it is appropriate to stop treatment and how to do so safely.

Children and adolescents

The safety and efficacy of pregabalin have not been established in children and adolescents (under 18 years of age), and therefore pregabalin should not be used in this age group.

Other medicines and Premax

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Pregabalin and certain medicines may interact with each other. When pregabalin is used together with certain medicines that have a sedative effect (including opioids), these effects may be enhanced, potentially leading to respiratory failure, coma, and death. The degree of dizziness, drowsiness, and reduced concentration may increase if pregabalin is taken together with other medicines containing:

Oxycodone – (used as an analgesic)

Lorazepam – (used to treat anxiety)

Alcohol

This medicine can be taken with oral contraceptives.

Taking Premax with food, drinks, and alcohol

Pregabalin tablets can be taken with or without food.

It is advised not to consume alcohol during treatment with pregabalin.

Pregnancy, breastfeeding, and fertility

You should not take pregabalin during pregnancy or breastfeeding unless your doctor has specifically instructed you to do so. The use of pregabalin during the first 3 months of pregnancy may cause congenital malformations in the fetus that require medical treatment. In a study reviewing data from women in Nordic countries who took pregabalin during the first 3 months of pregnancy, 6 out of every 100 babies had such congenital malformations. This compares with 4 out of every 100 babies born to women not treated with pregabalin in the study. Malformations reported include facial clefts, eyes, the nervous system (including the brain), kidneys, and genitals.

Women of childbearing potential should use an effective method of contraception. If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Driving and using machines

Pregabalin may cause dizziness, drowsiness, and reduced concentration. You should not drive, operate heavy machinery, or engage in other potentially hazardous activities until you know whether this medicine affects your ability to perform these tasks.

3. How to take Premax

Follow exactly the instructions given by your doctor for taking this medicine.

If in doubt, consult your doctor or pharmacist again. Do not take more medicine than prescribed.

Your doctor will determine the appropriate dose for you.

Pregabalin is for oral use only.

Peripheral and central neuropathic pain, epilepsy, or generalized anxiety disorder:

• Take the number of tablets prescribed by your doctor.
• The dose, adjusted according to your condition, is generally between 150 mg and 600 mg daily.
• Your doctor will instruct you to take pregabalin two or three times a day. If twice daily, take pregabalin once in the morning and once at night, approximately at the same time each day. If three times daily, take pregabalin in the morning, at midday, and at night, approximately at the same time each day.

If you feel the effect of pregabalin is too strong or too weak, inform your doctor or pharmacist.

If you are an elderly patient (over 65 years of age), you should take pregabalin as usual, unless you have kidney problems.

Your doctor may prescribe a different dosing regimen and/or different doses if you have kidney problems.

Swallow the tablet with water, without crushing or dissolving it.

The tablet may be divided into equal doses.

Continue taking pregabalin until your doctor tells you to stop.

If you take more Premax than you should

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately or call the Toxicology Information Service at: 91 562 04 20, indicating the medicine and the amount ingested.
As a result of taking more pregabalin than recommended, you may feel drowsy, confused, agitated, or restless. Seizures and loss of consciousness (coma) have also been reported.

If you forget to take Premax

It is important to take pregabalin tablets regularly at the same time each day. If you forget to take a dose, take it as soon as you remember, unless it is almost time for your next dose. In that case, continue with your next dose as normal. Do not take a double dose to make up for a missed dose.

If you stop taking Premax

Do not stop taking Premax suddenly. If you wish to discontinue Premax, speak to your doctor first. He or she will advise you on how to do so. If you are going to stop treatment, it should be done gradually over a minimum of one week.

After stopping short- or long-term treatment with Premax, you should be aware that you may experience certain adverse effects, known as withdrawal effects. These effects include sleep disturbances, headache, nausea, feelings of anxiety, diarrhea, flu-like symptoms, seizures, restlessness, depression, thoughts of harming yourself or suicide, pain, sweating, and dizziness. These effects may occur more frequently or severely if you have been taking Premax for a longer period of time. If you experience withdrawal effects, contact your doctor.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
